Cavedog Entertainment

On April 1, 1999, as an April Fool's Day joke, the company announced that due to legal problems with the U.S. Patent and Trademark Office, they had to rename the company as well as all their games and other trademarks. The company was now called "Frozen Yak Entertainment", and their main game "Total Annihilation" was renamed "Really Cool Wargame". Add-ons to the game and titles still in development at the time were also given new names. Cavedog even registered a new website complete with logos, pictures, and a press release. Interestingly, this "fake" website (www.frozenyak.com) is still online today (2010).
